There was no 'idiotic power game' we discussed what they were having for lunch before I left for work. I told him what we had in the house and gave him him the option of having dd1 come and collect my free meal for them to share.
I am past power games. I am past trying to get any help from him. I've done power games that did not involve the children by refusing to cook for him or wash for him all that happened is that I ended up with more take out cartons to clean up and huge piles of dirty washing on the stairs.
He said he would 'cook' chicken fingers, sweetcorn, peas and potato shapes for them. He normally does cook for them, albeit later than he should but never as late as he did yesterday. Dd1 said she would make angel delight for dessert for everyone and asked if I wanted some.
She did buy some jelly cubes (with her pocket money) to go with a tin of fruit earlier in the day to make herself and dd2 some jelly and fruit but DH took it off her and hid it so she would not 'make a mess' 
I had spent all morning cleaning the kitchen and dining room, so DH did not want her in there messing it up again. Why I don't know because she is fairly good at putting what she has used in the sink and wiping down any mess.
There was and still is food in the house that dd1 could have prepared herself, there was just no crisps and yoghurts left for them to pick at and only bananas left in the fruit bowl which dd1 does not like, there is a fruit stall just accross the road on weekends and bank holidays she could have made use of if she wanted to. She knows where I keep spare change, an apple only costs a couple of pence. She also had the option of coming to me and getting something from my work. I only work around the corner. She is allowed to call in alone during daylight hours.
Pastries are not an ideal lunch but as a weekend treat they're hardly going to kill them.
Had I not been working until 12am (so not in bed until after 1am after I'd had a cuppa etc.) the night before and then up at 7am to clean up before work and had I not been looking forward to having a sit down and some lunch before more washing and a busy evening shift I would have made them both omlettes or something.
I had no energy or time really (I had uniforms still to wash and dogs to walk before my next shift) to argue with either dd1 or DH about who was having what for lunch. They'd been at my mum's the night before and had been given a decent breakfast of eggs, beans and wholemeal toast and fruit at 9am, so I saw nothing wrong a pastry treat for lunch. I knew she would buy pastries at the shop it's what she always choses when she is allowed to pick a 'treat' lunch. It's flour, eggs and milk and butter, not aresenic. With a fruit or savoury filling. She went for cheese and onion pasties and an apple turnover each, like she always does. She would have warmed up some beans to go with the pasties were they not confiscated from her because DH had just put the chicken fingers and potato shapes in the oven while she was at the shop.
He didn't tell me he was doing that but had seen her at the shop so I assumed he knew she was buying lunch for herself since I do not like sweet pastries.
And yes DH needs a rocket up his arse or a nuclear bomb or I need to leave, but with no support from anywhere I find the prospect of that terrifying. I brought in a family support worker to help us and try and get him into counselling and us both in couples counselling or to help me leave, which is what they promised to do, but he will not engage with them or partake in counsellling. Everytime I mention wanting to leave to them because of lack of support they point out how much childcare he does when I work and his 'illnesses', like I'm not doing the same when he is working

I get the same response from my family when I tell them how much I am struggling.
Right at this moment in time I am still far too tired and stressed as well as now mulling over the prospect that some drunken eejit might not be some just some druken eejit and might actually try to 'do me in' to even think about what I am going to do next.
DH is still being nice and has told me to phone the police and then him immediately if the drunken tosser turns up at work today and he will come straight home from work.
